Recently, several works have analyzed the topic of Bluetooth Low Energy (BLE) device discovery through analytical or simulation models limited to version 4.x. Non-connectable and non-scannable undirected advertising has been shown to be a reliable alternative for discovering a high number of devices in a relatively short time period. However, new features of Bluetooth 5.0 allow us to define a variant on the device discovery process, based on BLE scannable undirected advertising events, which results in higher discovering capacities and also lower power consumption. In order to characterize this new device discovery process, we experimentally model the real device behavior of BLE scannable undirected advertising events. Non-detection packet probability, discovery probability, and discovery latency for a varying number of devices and parameters are compared by simulations and experimental measurements. We demonstrate that our proposal outperforms previous works, diminishing the discovery time and increasing the potential user device density. A mathematical model is also developed in order to easily obtain a measure of the potential capacity in high density scenarios. info:eu-repo/grantAgreement/ES/MINECO/TEC2014-58341-C4-2-R info:eu-repo/grantAgreement/ES/MINECO/TEC2014-60258-C2-2-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.475 2017 CHEMISTRY, ANALYTICAL 30 / 80 = 0.375 2017 Q2 T2 INSTRUMENTS & INSTRUMENTATION 16 / 61 = 0.262 2017 Q2 T1 ELECTROCHEMISTRY 15 / 28 = 0.536 2017 Q3 T2 0.584 2017 Analytical Chemistry 2017 Q2 Atomic and Molecular Physics, and Optics 2017 Q2 Medicine (miscellaneous) 2017 Q2 Electrical and Electronic Engineering 2017 Q2 Instrumentation 2017 Q2 Biochemistry 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Perez-Diaz-De-Cerio, David (orcid)0000-0003-2664-6339 Valdovinos, Antonio Universidad de Zaragoza Valenzuela, José Luis 5008 560 Universidad de Zaragoza Dpto.
